Workshop
SLAC, July 2009

2. Outline
Completed Work
2. Ongoing Work
3. Future Work Scope

3. Work Done Since the Collaboration
1. CERN HDX11 Cu Structure
SLAC Provided RF feed related components
Electrical polishing and high power tested in the NLCTA
2. CERN TD18_VG2.4_QURD
High power testing
3. SLAC T28_vg2.9 (T26) Structure
Use T53VG3MC and high power tested in the NLCTA since June 2008
4. CERN T18_VG2.4_DISK
5. KEK/SLAC 4 x T18_VG2.4_DISC Structures
Two with SLAC flanges, which have been high power tested at NLCTA
One with KEK flanges, which also has been high power tested at KEK
One with KEK flanges has been shipped to KEK

4. Ongoing Work 1. CERN T24_VG1.8_DISK #1 (Tank) 2. C10 Structures:
Assembly
High power testing
2. C10 Structures:
C10_VG 1.35 #1
Vacuum baked for 8 hours at 550 Cº
Microwave measurement and tuning completed.
Installation at ASTA is nearly completed.
High power test underway (60 ns, 90 MV/m)
C10_VG 1.35 #2 final brazed and wait for assembly after 1st test completion
C10_VG 0.7 #1, #2 stacks bonded and ready to be assembled
C10_VG 2.25 #1, #2 and 2 x C10_VG 3.3 #1, #2
Addendum 4 is submitted three months ago, hopefully it will be processed soon

5. First C10_VG1.35 Structure

6. Measured S Parameters for the First C10_VG1.35 Structure
Tf ~ 26 ns

7. The First C10_VG1.35 Structure after tuning

8. Work for Future Structures
1. Two TD18_VG2.4_DISK #2, #3 Structures
Bonding fixtures under fabrication
Cup handling carriers purchased
Assembly, tuning and baking in July – August
One TD18 structure will be high power tested at SLAC in September
2. Ship T18_VG2.4_DISC #1 to CERN for studies
3. CERN TD24_VG1.8_DISK #1
Will ship to SLAC and high Power Testing
4. CERN T24_VG1.8_DISK (Sealed)
5. Plan to retest TD18_VG2.4_QUAD in ASTA
Hydrogen firing and vacuum baking
Reassembly and microwave check
6. CERN T18_VG2.4_DISC #5
High power testing
7. KEK 2xC10_VG1.35 #3, #4
Discussion underway, assembly, tuning and High power testing
8. KEK 2xCD10_VG1.35 #1, #2
9. CERN 2xCD10_VG1.35 #3, #4
Assembly and High power testing
